Piston rings ?

[jos 4 age]

Hello,
Is there any difference in piston rings between the small and big port ?
Replaced head gasket and piston rings 500km ago and it looks like the engine is using oil. Filled it up untill max on the dipstick and now it is half way between full and "empty".
Maybe it has to be broken in ?
I use different oil now, before I used Castrol 10w40 semi synt now using valavoline durablend 10w40 semi synt.

thanks
Jos

I dont know if there are differences between the piston rings of the high and low compression pistons, but if your engine was using oil before, then you might also consider changing your valve seals.

we changed the valve seals together with the pistonrings and head gasket.
before the enigine was not using oil

"NOTE: Make sure that you choose the correct ring for your 4A-GE! Earlier 4A-GEs have a 1.5 mm #1 compression ring vs. the newer 1.2 mm #1 compression rings!"

the rings are different.... also you must have the correct hone to match the rings to get them to "bed in" properly

so the rings for the small port are the ones mentioned 90-93 in the overview Michel H ?

[robokill]

for the late type. Yes, The other ones have the 18 mm pin.

I think it is normal for the engine to burn some oil while breakin' in.

I've done almost 1500 miles and I already added 1 liter of Castrol RS Formula 10W60 100% Synth
